For Quickbooks online, how do I generate end of year donor tax letters like I did for the desk version?

Hello there, @ljbukowski.

Right now, the ability to generate donation letters is unavailable in QuickBooks Online (QBO). As a workaround, you can create a transaction statement or pulling up the Sales by Donor Detail report to get the details you need per donor. 

Here's how to create a statement: 

1. Click + New from the left menu. 
2. Select Statement under Other.
3. Choose Transaction Statement as the Statement Type.
4. Set your desired period and choose the recipients.
5. Select Print or Preview at the bottom or select Save and close when you're done.

To create the Sales by Donor Detail report, refer to the steps below: 

1. Click Reports on the left panel.
2. Type Sales by Customer Detail on the search box.
3. Click the Customize button in the upper right-hand corner.
4. Maximize the Rows/Columns section, and then click the Change columns link.
5. Check the box for Donors.
6. Click Run report.

If this doesn't work for you, I'd suggest visiting our App Center. There are donation apps that can integrate with QBO and can sync with your financial data. This way, it'll be easier to gather everything you need to issue the donor letters.

You can stay in the know about feature releases and product updates by visiting the QuickBooks Blog. It also contains some tips on how to efficiently run the business.

Though you can create reports for managements purposes, QuickBooks won't create proper donor statements with the required text and read to mail or email.  Instead, use the BRC Donor Statements - QB Online , which will read your QB data (first exported from QB using reports) and create the statements without any additional data entry.
